Small Mounds, Knowth

An unusal feature of the Knowth complex site is a 'necklace' arrangement of smaller mounds about the large Site 1 mound we were discussing.

The archaeologists have discovered some 17 smaller mounds some undifferentiated, the remainder cruciform in style. The really odd thing about these features is their orientation, which denotes that they all face into Site 1, with one or two exceptions.

The area they occupy was found to contain a veritable history of Irish archaeology down through the ages, right up to the early medieval times. Considerable settlements appear to dot the landscape. I know elsewhere on this site I joke about the long length of time that has been taken over the excavations at Knowth, but now I believe it was warranted considering the complexity of activity around Knowth. But let us look first at the axis alignments of these smaller features.



sites 2-17

Now there are a few interesting axis points here, Site 1 marks the Mid-Winter sunset point for that latitude , Site 17 has a clear North-South absolute axis and is positioned outside the Eastern passageway entrance a little to the North of it. An excellent marker for cardinal axis purposes. Two sites, 12 and 13 are almost the same 152° and 153° respectively, if site 1 wasn't there they would point to The Moon's Southernly declination points on the horizon. Finally sites 6 and 9 , pointing to 103° and 97° respectively, Moon's rising equinox times?. They are curious these little sites, but most of them have been dated to after site 1's insertion, except sites 13 and 16 which appear to predate it if you support the 'scenario one' theory I laid out previously. I obviously will do more analysis on these at some time in the future, but they are intriguing none the less.



Preliminary Findings

1) A unique near double Zenith alignment of Vega and Arcturus occurs at Knowth between 5518 BC and 5541 BC.

2)Gnomon/Zenith post proposal for Mesolithic settlement in Knowth and initiation of agricultural practices there.

3)Proposal of 5100 BC for passage mound phases (prototype).

4)Sun/Moon shadow system for pillar/entrance stones outside Eastern and Western passages at site 1as Equinox adjustors and Metonic cycle indicators.

5)Pillar/kerbstone shadow system is a perpetual calendar for the equinoxes.

6)Possible correlation of double Zenith alignment with Alexander Gurshtein's 'First Constellations' theory for first sign of agricultural settlements in Mesolithic times.

7) Site 1 passage alignments a function of tracking and predicting lunar eclipses
